I forgot a step:
after the step 1)Power on ( Remote)
you have to open the tray without a disc and then continue with the other steps
2) Setup (Remote)
3) Mute (Remote)
4) Stop (Remote)
5) Zoom (Remote)

in your tv screen apears " set of all regions"
Try it , it´s safety , i made it and function for Daewoo DVDS200 .
